Publisher Description
A leading data visualization expert explores the negative—and positive—influences that charts have on our perception of truth.
Today, public conversations are increasingly driven by numbers. While charts, infographics, and diagrams can make us smarter, they can also deceive—intentionally or unintentionally. To be informed citizens, we must all be able to decode and use the visual information that politicians, journalists, and even our employers present us with each day. Demystifying an essential new literacy for our data-driven world, How Charts Lie examines contemporary examples ranging from election result infographics to global GDP maps and box office record charts, as well as an updated afterword on the graphics of the COVID-19 pandemic.

Visual journalism professor Cairo (The Truthful Art), who has consulted for Google and the Congressional Budget Office, provides a valuable guide to reading charts with a critical and nuanced eye. With the use of such graphics throughout media only increasing, Cairo insists, persuasively, that "just looking at charts, as if they were mere illustrations," is not enough; "we must learn to read them and interpret them correctly." After offering a guide to different kinds of charts, Cairo presents the different ways they can mislead, including by using the wrong data or concealing uncertainty. His examples of misleading charts include one from an antiabortion group purporting to show Planned Parenthood's cancer-screening and prevention services sharply declining while the abortions it provided sharply rose; Cairo patiently explains how the chart concealed and distorted information, such as by "using a different vertical scale for each variable." By also criticizing staunchly liberal New York Times columnist Paul Krugman for using a chart depicting the annual U.S. murder rate that omits data from more recent years, Cairo even-handedly demonstrates that the misuse of infographics is not confined to one political side. At a time of widespread concern over disinformation in the media, Cairo provides a valuable corrective to the acceptance of numbers, and their visual representation, as having objective truth.
